1. Mount the bracket to the mounting surface.
2. Knock out the bracket mounting hole in the
enclosure base and attach the enclosure to
the bracket.
3. Insert the mirror and circuit board.
For more information on the bracket mounting,
refer to the installation manual of the bracket.
Selecting the vertical angle of the mirror

– Avoid the following inside the monitoring
area:

tioning outlets
– heat sources (a minimum distance of
1.5 m to a radiator is necessary)
– windows
– small animals
– direct sunlight
– The detector cannot detect through glass.

Connection
Danger!
Injuries and damage of the detector
due to electricity are possible. Inspect
all connections to be correct before ap-
plying power.
3 |
– When using two or more detectors, the best
coverage is achieved by overlapping the
monitoring areas. The detectors do not af-
fect each other.
Installation preparations
1. Select a surface that is solid and free of
vibrations. In order to ensure the intru-
sion security of dropped ceilings, detect-
ors should monitor each other.
Mounting
Notice! Removing masking from the mirror ele-
ments leaves adhesive residue that pollutes the
mirror and leads to malfunction of the detector.
VdS requirements prohibit mirror masking.
1. To remove the cover, insert a thin blade
screwdriver into the notch at the bottom and
pry it open.
2. To remove the circuit board, press one of
the circuit board retainer tabs towards the
side of the enclosure and lift the circuit
board out of the enclosure base.

3. Slide the mirror out of its tracks.
Notice! To exchange the mirror, remove the
current mirror and slide the other mirror into
the tracks.
4. Open an appropriate wiring knockout by tap-
ping it with a screwdriver then route the wir-
ing through the opening.
5. For strain relief, attach the cable to the
cable tie with the supplied plastic tie-down.
Surface or corner mounting
1. Open either two of the four surface mount-
ing holes or the two corner mounting holes.
2. Use the enclosure as a template and mark
the location for the mounting screws.
3. Firmly mount the detector with appropriate
hardware depending on the mounting sur-
face (e.g., anchors).
4. Insert the mirror and circuit board.
Bracket mounting
Notice! When using a bracket, misalignment of
the detector might reduce the monitoring range.

Notice!
Do not coil excess wire inside the en-
closure or seal the wire entrance with
7
the plug provided.
Configuration
1. Set the sensitivity to one of the following
settings using the software:
Standard sensitivity (default)
– Protection against false alarms
– Tolerance to extreme environmental condi-
tions
– Not recommended for curtain mirror version
High sensitivity
– Recommended setting for any location
where an intruder is expected to cover only
a small portion of the monitoring area or
when quick catch performance is desired
– Tolerance to normal environmental condi-
tions
– High response sensitivity
